I was going to suggest saving in pdf and using a script to separate the
pages, but I see you are already doing that.

I use pdftex to produce presentations, but the cropbox issue is present
there as well.  I solve it by adding a large invisible rectangle that
belongs to all views, and contains all objects inside.  It is a little
bit of a pain, but it works. 

Is there any reason why the cropbox should not be set the same for all
pages in a pdf file?
